Research Issues and Challenges in Wireless Networks

The arrival of wireless technology has reduced the human efforts for accessing data at various locations by replacing wired infrastructure with wireless infrastructure and also providing access to devices having mobility. Since wireless devices need to be small and bandwidth constrained, some of the key challenges in wireless networks are Signal fading, mobility, data rate enhancements, minimizing size and cost, user security and (Quality of service) QoS. This paper is intended to provide the reader with an overview of the Research Issues and Challenges in wireless networks. Keyword-Wireless Local Area Networks (WLANs), IEEE 802.11, Quality of Service (QoS).
